6800 Gt Memory Clock Frequency

[Sargon]

I have a PNY 6800 GT AGP video card and the latest Nvidia drivers. My factory clock settings are 350/1000, but the Nvidia control panel shows them to be 350/2000. Is this anything to worry about, or is the display doubling the actual frequency?

That is not correct. The memory frequency should be around 1000mhz.

If its got DDR its real clock will be 1000mhz and its effective will be 2000mhz.

no 6800gt will come clocked @ 2ghz heh, not even today's high end cards have that high memory

 

although he's right. Real clock=500mhz, effective=1000mhz

 

i have a feeling the nvidia driver doubled it thinking that it was the real clock.

Hmm... so should I over-ride the default settings and "underclock" the card? It seems strange that it would pass the tests at double the factory clock frequency.

if the card was actually set to this i doubt you would even be able to boot as you will usually start getting artifacting @ about 1100mhz its probable just a glitch install Rivatuner see if it gives you the same values

It would have to be a cold day in hell (phase change cold or better) for someone to get a 6800GT to 2ghz.

With the Nvidia control panel memory frequency set to 2000 MHz, RivaTuner shows it as 500 MHz (1000 MHz effective)... so it appears to just be a bug with the Nvidia control panel.
